I also found a firmware update binary for the #Phylion #BN10 battery, but couldn't even figure out the MCU architecture at first glance.
(And I couldn't find a picture of the BMS PCB / don't want to open my battery yet to read the IC marking, if it even has one.)

Maybe someone recognizes the MCU from the screenshot (file is 40KB).

Unsure if it would even help me at all, but I felt a peek couldn't hurt ^^

But I'm mainly curious if anyone already has a bit more information on this whole topic by chance, before I plunge blindly into these uncharted waters :D

#Fischer, #Brose #Drive C motor, #Phylion #BN10 battery, #Joycube

[sorry for the many #, but that's the only good way to find toots again afaik]

But even finding the #Fischer / #Phylion charging plug for sale seems to be pretty impossible.
There are a handful of OEM charger manufacturers, but no one sells the plug / cable assembly without a charger.
And it doesn't even have a real designation, it's simply called "#trapezoid 5-pin" everywhere (DE: #Trapezstecker)
Except for the custom metal shield it appears to follow Sub-D dimensions for pin pitch and diameter.

Anybody got an idea how it's called or where to get one by chance?
